text-indent: 27pt; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;"&gt;Generally, the warranty period for our power quality products is 12 months from the date of commissioning or 18 months from the date of shipment from Active Power, whichever period is shorter. Occasionally, we offer longer warranty periods to certain customers. The warranty period for products sold to our primary OEM customer, Caterpillar, is 12 months from the date of shipment to the end-user, or up to 36 months from shipment. This is dependent upon Caterpillar complying with our storage requirements for our products in order to preserve this warranty period beyond the standard 18-month limit. We provide for the estimated cost of product warranties at the time revenue is recognized and this accrual is included in accrued expenses and long-term liabilities on the accompanying consolidated balance sheet.&lt;/div&gt;&lt;div style="text-align: left;

text-indent: 27pt; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;"&gt;In general, we recognize revenue when four criteria are met: (i) persuasive evidence that an arrangement exists; (ii) delivery has occurred or services have been rendered; (iii) the sales price is fixed or determinable; and (iv) collectability is reasonably assured. Revenue-generating transactions generally fall into one of the following categories of revenue recognition:&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt;&lt;table cellpadding="0" cellspacing="0" class="DSPFListTable" style="width: 100%; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;&lt;tr&gt;&lt;td style="width: 27pt;"&gt;&lt;/td&gt;&lt;td style="width: 18pt; font-family: ''Times New Roman'', Times, serif; font-size: 10pt; vertical-align: top; align: right;"&gt;&amp;#9679;&lt;/td&gt;&lt;td style="text-align: justify; width: auto; font-family: ''Times New Roman'', Times, serif; font-size: 10pt; vertical-align: top;"&gt;We recognize product revenue at the time of shipment for substantially all products sold directly to customers and through distributors because title and risk of loss pass on delivery to the common carrier. Our customers and distributors do not have the right to return products. If title and risk of loss pass at some other point in time, we recognize such revenue for our customers when the product is delivered to the customer and title and risk of loss have passed. &amp;#160;We may enter into bill-and-hold arrangements and when this occurs delivery may not be present, but other criteria are reviewed to determine the proper timing of revenue recognition.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: left;"&gt;&lt;table cellpadding="0" cellspacing="0" class="DSPFListTable" style="width: 100%; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;&lt;tr&gt;&lt;td style="width: 27pt;"&gt;&lt;/td&gt;&lt;td style="width: 18pt; font-family: ''Times New Roman'', Times, serif; font-size: 10pt; vertical-align: top; align: right;"&gt;&amp;#9679;&lt;/td&gt;&lt;td style="text-align: left; width: auto; font-family: ''Times New Roman'', Times, serif; font-size: 10pt; vertical-align: top;"&gt;We recognize installation and service and maintenance revenue at the time the service is performed.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt;&lt;table cellpadding="0" cellspacing="0" class="DSPFListTable" style="width: 100%; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;&lt;tr&gt;&lt;td style="width: 27pt;"&gt;&lt;/td&gt;&lt;td style="width: 18pt; font-family: ''Times New Roman'', Times, serif; font-size: 10pt; vertical-align: top; align: right;"&gt;&amp;#9679;&lt;/td&gt;&lt;td style="text-align: justify; width: auto; font-family: ''Times New Roman'', Times, serif; font-size: 10pt; vertical-align: top;"&gt;We recognize revenue associated with extended maintenance agreements (&amp;#8220;EMAs&amp;#8221;) over the life of the contracts using the straight-line method, which approximates the expected timing in which applicable services are performed. Amounts collected in advance of revenue recognition are recorded as a current or long-term liability based on the time from the balance sheet date to the future date of revenue recognition.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify;"&gt;&lt;table cellpadding="0" cellspacing="0" class="DSPFListTable" style="width: 100%; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;&lt;tr&gt;&lt;td style="width: 27pt;"&gt;&lt;/td&gt;&lt;td style="width: 18pt; font-family: ''Times New Roman'', Times, serif; font-size: 10pt; vertical-align: top; align: right;"&gt;&amp;#9679;&lt;/td&gt;&lt;td style="text-align: justify; width: auto; font-family: ''Times New Roman'', Times, serif; font-size: 10pt; vertical-align: top;"&gt;We recognize revenue on certain rental programs over the life of the rental agreement using the straight-line method. Amounts collected in advance of revenue recognition are recorded as a current or long-term liability based on the time from the balance sheet date to the future date of revenue recognition.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: left;"&gt;&lt;table cellpadding="0" cellspacing="0" class="DSPFListTable" style="width: 100%; font-family: 'Times New Roman', Times, serif; font-size: 10pt;"&gt;&lt;tr&gt;&lt;td style="width: 27pt;"&gt;&lt;/td&gt;&lt;td style="width: 18pt; font-family: ''Times New Roman'', Times, serif; font-size: 10pt; vertical-align: top; align: right;"&gt;&amp;#9679;&lt;/td&gt;&lt;td style="text-align: left; width: auto; font-family: ''Times New Roman'', Times, serif; font-size: 10pt; vertical-align: top;"&gt;Shipping costs reimbursed by the customer are included in revenue.&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; text-indent: 27pt; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;"&gt;When collectability is not reasonably assured, we defer revenue and will recognize revenue on a cost recovery basis as payments are received.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; text-indent: 27pt; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;"&gt;Multiple element arrangements (&amp;#8220;MEAs&amp;#8221;) are arrangements to sell products to customers that frequently include multiple deliverables. Our most significant MEAs include the sale of one or more of our CleanSource&amp;#174; UPS or PowerHouse products, combined with one or more of the following products: design services, project management, commissioning and installation services, spare parts or consumables, and EMAs. Delivery of the various products or performance of services within the arrangement may or may not coincide. Certain services related to design and consulting may occur prior to delivery of product and commissioning and installation typically take place within six months of product delivery, depending upon customer requirements. EMAs, consumables, and repair, maintenance or consulting services generally are delivered over a period of one to five years. In certain arrangements, revenue recognized is limited to the amount invoiced or received that is not contingent on the delivery of future products and services.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; text-indent: 27pt; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;"&gt;When arrangements include multiple elements, we allocate revenue to each element based on the relative selling price and recognize revenue when the elements have stand-alone value and the four criteria for revenue recognition have been met. We establish the selling price of each element based on Vendor Specific Objective Evidence (&amp;#8220;VSOE&amp;#8221;) if available, Third Party Evidence (&amp;#8220;TPE&amp;#8221;) if VSOE is not available, or Best Estimate of Selling Price (&amp;#8220;BESP&amp;#8221;) if neither VSOE nor TPE is available. We generally determine selling price based on amounts charged separately for the delivered and undelivered elements to similar customers in stand-alone sales of the specific elements. When arrangements include an EMA, we recognize revenue related to the EMA at the stated contractual price on a straight-line basis over the life of the agreement.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div style="text-align: justify; text-indent: 27pt; font-family: ''Times New Roman'', Times, serif; font-size: 10pt;"&gt;Any taxes imposed by governmental authorities on our revenue-producing transactions with customers are shown in our consolidated statements of operations on a net-basis; that is, excluded from our reported revenues.&lt;/div&gt;&lt;/div&gt;</us-gaap:SupplementalBalanceSheetDisclosuresTextBlock>
